Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an extended container and vehicle device. Background Technology

[0002] Containers are standardized carriers in the fields of logistics and space applications. They are characterized by convenient transportation and reliable structure, and are widely used in scenarios such as warehousing and temporary space construction.

[0003] In existing technologies, the internal space of commercially available standard shipping containers is generally too small, making it difficult to meet the demand for large-capacity display space in scenarios such as temporary exhibitions and mobile advertising. Existing similar solutions mostly attempt to solve the space problem by slightly expanding the cabin or adding external structures, but they generally suffer from insufficient expansion capabilities, poor structural stability, and low operational efficiency, which limits their applicability in scenarios requiring large-area, flexible space deployment. Utility Model Content

[0004] The purpose of this application is to provide an expansion container and vehicle device that can drive the expansion container to extend outwards from the main container via a drive component, so that multiple flaps unfold and form a flat top and bottom wall, significantly increasing the internal usable area of ​​the container.

[0005] In a first aspect, this utility model provides an extended container, comprising:

[0006] main box;

[0007] An expandable box is provided at least once. The expandable box is retractably provided on one side of the main box and communicates with the main box. The expandable box includes a side wall, a top wall and a bottom wall. The top wall and the bottom wall are respectively connected to the side wall. The top wall and the bottom wall each include multiple foldable and connectable flaps.

[0008] A driving component, connected to the expansion box, is used to drive the expansion box to extend outward or retract inward to the main box.

[0009] The extended container has a transport state and an extended state. In the transport state, the extended container is located inside the main container, and the multiple flaps are folded together. In the extended state, the extended container extends outward from the main container, and the multiple flaps are on the same plane.

[0010] Beneficial effects: This expandable container, with its dual transport and expandable states, allows for efficient transport. During transport, the expandable container is adjusted to its transport state, folding and storing within the main container, resulting in a compact structure that facilitates transport. When greater container space is needed, a drive mechanism extends the expandable container outwards from the main container, unfolding multiple flaps to form flat top and bottom walls. Connecting with the main container significantly increases usable internal space, breaking through the fixed space limitations of traditional containers and meeting the demands for large-capacity display space in temporary exhibitions, mobile advertising, and other scenarios.

[0011] In addition, the expansion box and the main box are linked by a drive component to extend and retract, forming an integrated rigid frame structure after extension. After the flap is folded and unfolded, it forms a continuous and flat top and bottom surface, which improves the overall support strength and avoids the hidden danger of easy shaking of traditional external addition structures. This ensures that the box is stable and reliable in the extended state, and is suitable for scenarios with frequent personnel activities or long-term display.

[0012] Meanwhile, the drive unit can automatically extend or retract the expansion box without the need for manual splicing, disassembly of the flip panels or structural adjustments, which greatly shortens the space deployment time, reduces labor costs, and meets the needs of scenarios that require rapid setup and flexible movement. It is especially suitable for mobile advertising or emergency response scenarios that require frequent site changes.

[0013] In one optional embodiment, along the length of the flap, a plurality of support seats are provided at intervals at the bottom of the flap, and two adjacent flaps are rotatably connected by the support seats and a rotating shaft.

[0014] Beneficial effects: By setting support seats at intervals along the length of the flap and connecting them with a pivot, the load borne by the flap (such as the weight of personnel and the pressure of equipment) can be evenly transferred to the pivot and the main frame through multiple support seats. This avoids deformation or breakage caused by single-point stress, enhances the bending resistance of the flap connection, and keeps the top or bottom wall flat and stable after unfolding. It is especially suitable for floor scenarios with high load-bearing requirements. It can effectively avoid the sagging or shaking problems that may occur with traditional flexible hinge connections, and improve the reliability and safety of the overall structure.

[0015] In one optional embodiment, a limiting member is provided at the bottom of the flap;

[0016] In the extended state, the limiting members of two adjacent flaps abut against each other, so that the flaps are on the same plane.

[0017] Beneficial effects: The limiting components at the bottom of the flip panel abut against each other in the extended state, forcibly limiting the rotation angle of the flip panel through mechanical stopping action, ensuring that adjacent flip panels are on the same plane. This can eliminate the problem of height difference between flip panels caused by gaps or uneven force in traditional hinge connections. It is especially suitable for scenarios with high requirements for floor flatness (such as exhibition spaces and mobile office areas), preventing people from tripping or equipment from being placed unstable, and improving safety and user experience.

[0018] In one optional embodiment, the expansion box is provided with rotatable first doors at both ends;

[0019] In the transport state, the plane of the first door is parallel to the plane of the side wall;

[0020] In the extended state, the plane of the first door is perpendicular to the plane of the side wall.

[0021] Beneficial effects: In the transport state, the first door is parallel to the side wall plane, fitting snugly against the side wall of the extended container, avoiding protruding structures that increase transport volume or cause collision risks, and meeting the strict size restrictions for containers in road and rail transport scenarios. When in the extended state, the first door rotates to be perpendicular to the side wall plane, forming an independent entrance and exit, without the need for additional door installation or removal. Simultaneously, in the extended state, the first door, after being vertically locked, forms a rigid support structure that can withstand certain external forces (such as crowds pushing), avoiding the safety hazards caused by the swaying of traditional external doors, making it particularly suitable for exhibition scenarios with high population density.

[0022] In one optional embodiment, the driving component includes a hydraulic cylinder and a telescopic tube, with the hydraulic cylinder and the telescopic tube arranged parallel to each other; one end of both the hydraulic cylinder and the telescopic tube is connected to the main housing, and the other end of both is connected to the expansion housing.

[0023] Beneficial effects: The hydraulic cylinder and telescopic tube are arranged in parallel to form a dual-support drive structure. The hydraulic cylinder provides the main driving force, propelling the expansion box to extend and retract smoothly; the telescopic tube can act as a mechanical support component, simultaneously bearing lateral and longitudinal loads, avoiding piston rod bending or seal wear caused by the hydraulic cylinder bearing only the force, making it especially suitable for heavy-duty scenarios with large-sized expansion boxes.

[0024] In one alternative embodiment, two hydraulic cylinders are provided, and the telescopic tube is located between the two hydraulic cylinders.

[0025] Beneficial effects: The dual cylinders and the intermediate telescopic tube form a rigid triangular support system, significantly improving the torsional resistance of the drive system. When the extension box is subjected to asymmetrical loads, the telescopic tube can quickly transmit the reaction force through mechanical rigidity, reducing the bending moment borne by the cylinder piston rod, avoiding wear of the seals or deformation of the cylinder body due to excessive lateral force, and extending the service life of the hydraulic system.

[0026] In one alternative embodiment, one end of the main housing is provided with a rotatable second door, and one side of the second door is provided with a stepped structure.

[0027] Beneficial effects: The second door has a stepped structure, eliminating the need for additional stairs or ramps. During transportation, the second door rotates and closes flush with the main body, saving space. When in use, the second door rotates and lands, and the stepped structure automatically unfolds to form an upper and lower passage, achieving "one door for two uses," reducing equipment redundancy and improving space utilization.

[0028] In one optional embodiment, there are two expansion boxes, which are respectively located on opposite sides of the main box.

[0029] Beneficial effects: Two expandable compartments are symmetrically positioned on both sides of the main compartment, allowing for simultaneous extension to both sides, thus expanding the internal space laterally. Compared to single-sided expansion, this significantly increases the usable space inside the compartment. The symmetrical structure balances the load on both sides of the compartment, avoiding transportation stability issues caused by uneven weight distribution.

[0030] In one alternative embodiment, the top of the main housing is covered with photovoltaic panels.

[0031] Beneficial effects: By installing photovoltaic panels on the top of the main container, the photovoltaic panels convert solar energy into electrical energy, which is then stored through an energy storage system to power equipment such as lighting, air conditioning, and displays inside the container, reducing dependence on the external power grid.

[0032] Secondly, this utility model also provides a vehicle device, comprising:

[0033] Vehicle body;

[0034] The container is extended, with the main container body detachably mounted on the vehicle body.

[0035] Beneficial effects: Because this vehicle device is equipped with an expandable container, it can directly inherit the beneficial effects of the expandable container in terms of space expansion, structural stability, and operational efficiency, which will not be repeated here.

[0051] In related technologies, the internal space of commercially available standard shipping containers is generally too small, making it difficult to meet the demand for large-capacity display space in scenarios such as temporary exhibitions and mobile advertising. Existing similar solutions mostly attempt to solve the space problem by slightly expanding the cabin or adding external structures, but they generally suffer from insufficient expansion capabilities, poor structural stability, and low operational efficiency, which limits their applicability in scenarios requiring large-area, flexible space deployment.

[0052] During the research and development process of this application, in order to overcome the limitations of the internal space of standard shipping containers, the team initially tried to increase the volume by lengthening the container. While this solution significantly expanded the vertical space of the container, such as extending the length of a traditional 20-foot container from 5.9 meters to 8 meters, thus increasing the cargo loading depth, the width (standard 2.438 meters) remained limited, resulting in a long and narrow internal space that could not meet the needs of temporary exhibition halls, mobile offices, and other scenarios requiring open and well-organized spaces. For example, in exhibition setup, narrow spaces cannot accommodate the circular display flow of large exhibits, and it is difficult to arrange open workstations for multiple people to collaborate in office areas. At the same time, excessively long containers have many drawbacks during transportation, not only increasing the turning radius of vehicles and reducing road traffic flexibility, but also potentially facing strict regulatory restrictions and approval processes due to oversized transport, leading to a significant increase in transportation costs.

[0053] Based on this, the inventors of this application have redesigned the container. Since the expandable container has both a transport state and an expandable state, when transporting the expandable container, it is adjusted to the transport state, with the expandable body folded and stored inside the main container, resulting in a compact structure that facilitates transportation. When a larger container space is needed, a drive mechanism extends the expandable body outwards from the main container, causing multiple flaps to unfold and form flat top and bottom walls. After connecting with the main container, this significantly increases the internal usable area, breaking through the fixed space limitations of traditional containers and meeting the needs of temporary exhibitions, mobile advertising, and other scenarios requiring large-capacity display space.

[0054] In addition, the expansion box and the main box are linked by a drive component to extend and retract, forming an integrated rigid frame structure after extension. After the flap is folded and unfolded, it forms a continuous and flat top and bottom surface, which improves the overall support strength and avoids the hidden danger of easy shaking of traditional external addition structures. This ensures that the box is stable and reliable in the extended state, and is suitable for scenarios with frequent personnel activities or long-term display.

[0055] Meanwhile, the drive unit can automatically extend or retract the expansion box without the need for manual splicing, disassembly of the flip panels or structural adjustments, which greatly shortens the space deployment time, reduces labor costs, and meets the needs of scenarios that require rapid setup and flexible movement. It is especially suitable for mobile advertising or emergency response scenarios that require frequent site changes.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0057] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0058] According to embodiments of the present invention, on the one hand, such as Figures 1 to 10 As shown, an extended container is provided, including a main container 100 and an extended container 200.

[0059] Specifically, such as Figures 1 to 4 As shown, at least one expandable enclosure 200 is provided, wherein the expandable enclosure 200 is retractably disposed on one side of the main enclosure 100 and is connected to the main enclosure 100. The expandable enclosure 200 includes a side wall 210, a top wall 220, and a bottom wall 230, with the top wall 220 and bottom wall 230 respectively connected to the side wall 210. Both the top wall 220 and the bottom wall 230 include multiple foldable and connectable flaps 231.

[0060] Specifically, such as Figure 1 As shown, the drive unit 300 is connected to the expansion box 200. The drive unit 300 is used to drive the expansion box 200 to extend to the outside of the main box 100, or to drive the expansion box 200 to retract to the inside of the main box 100.

[0061] Specifically, such as Figures 1 to 4 As shown, the expandable container has a transport state and an expandable state. In the transport state, the expandable container 200 is located inside the main container 100, and multiple flaps 231 are folded together. In the expandable state, the expandable container 200 is driven by the drive unit 300 to extend outward from the main container 100, and the multiple flaps 231 are on the same plane.

[0062] This expandable container, having both a transport and an expanded state, allows for convenient transport when transported. In the transport state, the expandable container 200 is folded and stored within the main container 100, resulting in a compact structure. When more container space is needed, the expandable container 200 extends outwards from the main container 100 via a drive unit 300. This unfolds multiple flaps 231, forming a flat top wall 220 and bottom wall 230, which, when connected to the main container 100, significantly increases the usable internal area. This overcomes the limitations of traditional fixed container space and meets the demand for large-capacity display space in scenarios such as temporary exhibitions and mobile advertising.

[0063] In addition, the extension box 200 and the main box 100 are linked to extend and retract through the drive component 300. After extension, they form an integrated rigid frame structure. After the flap 231 is folded and unfolded, it forms a continuous and flat top wall 220 and bottom wall 230, which improves the overall support strength and avoids the hidden danger of easy shaking of traditional external added structures. It ensures that the box is stable and reliable in the extended state and is suitable for scenarios with frequent personnel activities or long-term display.

[0064] Meanwhile, the drive unit 300 can automatically drive the extension box 200 to extend or retract, eliminating the need for manual splicing, disassembly of the flip panel 231, or structural adjustments. This significantly shortens the space deployment time, reduces labor costs, and meets the needs of scenarios requiring rapid setup and flexible movement. It is especially suitable for mobile advertising or emergency response scenarios that require frequent site changes.

[0065] Specifically, one, two, three, etc., expansion boxes 200 can be provided. In this embodiment of the application, the number of expansion boxes 200 is not specifically limited.

[0066] Specifically, multiple flaps 231 can be folded together by means of hinge components or by means of flexible connecting strips. In this embodiment, no specific restrictions are placed on the foldable connection method of the flaps 231.

[0067] For example, adjacent flaps 231 are hinged end to end by a hinge assembly (such as a hinge or pin) to form a foldable chain structure. For instance, one edge of each flap 231 is fixed to the corresponding edge of the adjacent flap 231 by a hinge, allowing the flaps 231 to rotate and fold about the hinge axis.

[0068] Specifically, the drive component 300 can be selected from hydraulic drive systems, electric drive systems, pneumatic drive systems, etc. In this embodiment, the type of drive component 300 is not specifically limited.

[0069] In one embodiment, such as Figures 7 to 9 As shown, the bottom of the flap 231 is provided with multiple support seats 2311. The multiple support seats 2311 are spaced apart along the length of the flap 231. Two adjacent flaps 231 are rotatably connected by the support seats 2311 and the rotating shaft 2312.

[0070] Support seats 2311 are spaced apart along the length of the flap 231 and connected by a pivot 2312. The load (such as personnel weight and equipment pressure) borne by the flap 231 can be evenly transferred to the pivot 2312 and the main housing 100 frame through multiple support seats 2311. This avoids deformation or breakage caused by single-point stress, enhances the bending resistance of the flap 231 connection, and keeps the top wall 220 or bottom wall 230 flat and stable after unfolding. It is especially suitable for floor scenarios with high load-bearing requirements. It can effectively avoid the sagging or shaking problems that may occur with traditional flexible hinge connections and improve the reliability and safety of the overall structure.

[0071] In addition, the two adjacent flaps 231 are connected by the cooperation of the support base 2311 and the rotating shaft 2312, so that the adjacent flaps 231 can fit tightly after rotating around the rotating shaft 2312, which greatly reduces the space occupied in the folded state and minimizes the volume when the extended container 200 is retracted into the main container 100, thus meeting the size restriction requirements of road transportation for containers.

[0072] In one embodiment, such as Figures 7 to 9 As shown, the bottom of the flap 231 is provided with a limiting member 2313. In the extended state, the limiting members 2313 of two adjacent flaps 231 abut against each other, so that the flaps 231 are on the same plane.

[0073] The limiting members 2313 at the bottom of the flip panel 231 abut against each other in the extended state, and forcibly limit the rotation angle of the flip panel 231 through mechanical stop action, ensuring that adjacent flip panels 231 are on the same plane. This can eliminate the problem of height difference of the flip panels 231 caused by gaps or uneven force in traditional hinge connections. It is especially suitable for scenarios with high requirements for floor flatness (such as exhibition spaces and mobile office areas), avoids people tripping or unstable equipment placement, and improves safety and user experience.

[0074] Specifically, the mechanical positioning function of the limiting member 2313 can be linked with the driving member 300. When the flap 231 unfolds to the preset position, the limiting member 2313 abuts against the trigger limit switch or sensor and automatically stops the driving action. There is no need for an additional control system to accurately calculate the displacement, which reduces the complexity of automation design and avoids structural damage caused by over-extension, thus improving operational reliability.

[0075] Specifically, the rigid contact interface formed by the abutment of the limiting member 2313 can directly transfer the load of adjacent flaps 231 through the limiting member 2313, forming a continuous support system. For example, when people walk on the floor flap 231, the load can be quickly distributed to the entire expansion box 200 frame through the limiting member 2313, reducing the bending deformation of a single flap 231 and improving the overall rigidity of the structure.

[0076] In one embodiment, such as Figure 1As shown, the expansion box 200 has a first door 240 at each end, and the first door 240 is rotatably mounted on the expansion box 200. In the transport state, the plane of the first door 240 is parallel to the plane of the side wall 210. In the extended state, the plane of the first door 240 is perpendicular to the plane of the side wall 210.

[0077] In the transport state, the first door 240 is parallel to the plane of the side wall 210 and can fit snugly against the side wall 210 of the extended container 200, avoiding the increase in transport volume or the risk of collision caused by protruding structures, and meeting the strict size restrictions of containers in road and rail transport scenarios. When in the extended state, the first door 240 rotates to be perpendicular to the plane of the side wall 210, forming an independent entrance and exit, without the need for additional door panel installation or removal. At the same time, in the extended state, the first door 240 forms a rigid support structure after being vertically locked, which can withstand a certain amount of external force (such as crowd pushing), avoiding the safety hazards caused by the shaking of traditional external doors, and is especially suitable for exhibition scenarios with dense crowds.

[0078] Specifically, the first door 240 is fixed to the expansion box 200 by a rotatable connection (such as a hinge or a rotating shaft 2312), without the need for a complex folding or storage mechanism.

[0079] In one embodiment, such as Figure 5 and Figure 6 As shown, the drive unit 300 includes a hydraulic cylinder 310 and a telescopic tube 320, with the hydraulic cylinder 310 and the telescopic tube 320 arranged in parallel. One end of both the hydraulic cylinder 310 and the telescopic tube 320 is connected to the main housing 100, and the other end is connected to the extension housing 200.

[0080] The hydraulic cylinder 310 and the telescopic tube 320 are arranged in parallel to form a dual-support drive structure. The hydraulic cylinder 310 provides the main driving force to push the extension box 200 to extend and retract smoothly; the telescopic tube 320 can serve as a mechanical support component, simultaneously bearing lateral and longitudinal loads, avoiding piston rod bending or seal wear caused by the hydraulic cylinder 310 bearing force alone, which is especially suitable for heavy-duty scenarios of large-size extension boxes 200.

[0081] Specifically, the parallel structure of the hydraulic cylinder 310 and the telescopic tube 320 can adopt a modular pre-installation design: one end of both is fixed to the same mounting base of the main housing 100, and the other end is connected to the expansion housing 200. During installation, only the parallelism needs to be calibrated, without the need for complex positioning.

[0082] Specifically, the telescopic tube 320 can be a sleeve-type telescopic structure, composed of multiple concentric metal sleeves (such as stainless steel or aluminum alloy) nested together, with keyways or guide rails limiting the movement between the sections, allowing it to extend and retract along the axis. In this embodiment, the type of telescopic tube 320 is not specifically limited.

[0083] In one embodiment, such as Figure 5 and Figure 6 As shown, there are two hydraulic cylinders 310, and the telescopic tube 320 is located between the two hydraulic cylinders 310.

[0084] The dual hydraulic cylinders 310 and the intermediate telescopic tube 320 form a rigid triangular support system, significantly improving the torsional resistance of the drive system. When the extension housing 200 is subjected to asymmetrical loads, the telescopic tube 320 can quickly transmit the reaction force through mechanical rigidity, reducing the bending moment borne by the piston rod of the hydraulic cylinder 310, avoiding wear of the seals or deformation of the cylinder body due to excessive lateral force, and extending the service life of the hydraulic system.

[0085] In one embodiment, such as Figure 1 and Figure 10 As shown, a second door 110 is provided at one end of the main box 100. The second door 110 is rotatably mounted on the main box 100, and a stepped structure 111 is provided on one side of the second door 110.

[0086] The second door 110 is equipped with a stepped structure 111, eliminating the need for additional stairs or ramps. During transportation, the second door 110 rotates and closes to be flush with the main box 100, saving space. When in use, the second door 110 rotates and lands, and the stepped structure 111 automatically unfolds to form an upper and lower passage, achieving "one door for two purposes", reducing equipment redundancy and improving space utilization.

[0087] Specifically, the stair structure 111 is integrated with the door design, and the stair treads can be designed with anti-slip textures or lighting devices according to ergonomics to avoid the swaying or improper installation problems of traditional external staircases.

[0088] In one embodiment, such as Figure 1 As shown, there are two expansion boxes 200, which are respectively located on opposite sides of the main box 100.

[0089] Two extendable compartments 200 are symmetrically positioned on either side of the main compartment 100, allowing them to extend simultaneously to both sides, thus expanding the internal space laterally. Compared to single-sided extension, this significantly increases the usable space inside the compartment. The symmetrical structure balances the load on both sides of the compartment, avoiding transportation stability issues caused by uneven weight distribution.

[0090] Specifically, after the two expansion boxes 200 are expanded on both sides, the internal space can be flexibly divided into multiple functional areas, such as the display area on the left, the negotiation area on the right, and the central passage of the main box 100.

[0091] In one embodiment, the top of the main housing 100 is covered with photovoltaic panels.

[0092] By installing photovoltaic panels on the top of the main container 100, the photovoltaic panels convert solar energy into electrical energy, which is then stored through an energy storage system to power equipment such as lighting, air conditioning, and displays inside the container, reducing dependence on the external power grid.

[0093] According to an embodiment of the present invention, on the other hand, as... Figures 1 to 10 As shown, a vehicle assembly is also provided, including a vehicle body (not shown) and an extended container.

[0094] Specifically, the main body 100 is detachably mounted on the vehicle body.

[0095] Because this vehicle is equipped with an expandable container, it can directly inherit the beneficial effects of the expandable container in terms of space expansion, structural stability, and operational efficiency, which will not be repeated here.
